It had all started with a TV show about swingers. Sarah and I had spent our Friday night watching a few episodes of a show all about people that swap sexual partners. She talked about how she would not be able to handle watching me with another woman. I had totally understood of course, as I didn’t imagine I could handle watching her with another man either.

However, it was clear watching other people swap partners had gotten her very turned on. As soon as the show was over, she had taken me straight into our bedroom. Where she ripped off my clothes and mounted me. She had been so wet and horny. I had easily slipped inside of her warm tunnel.

Sarah loved to dirty talk during sex and she knew it always really got me going. She would beg me to fuck her harder with my big cock. The truth was my cock was only average at best. She had never complained about my size. But deep down I knew, she wished I was bigger.

She was starting to moan louder right into my ear, as she pressed herself against me. Our bodies were covered in sweat, the smell of sex strong in the air. She was whispering ‘fuck me’ and biting down on my ear lobe. I was getting close to cumming when she asked something I really didn’t expect.

“James, could you handle watching me with another man?” she asked, in a desperate, pleading moan.

I was taken aback. I opened my eyes and looked at her. Sarah had her head back, eyes closed, and was biting her lip. She looked in ecstasy. I lent in and began planting nibbling kisses on her collar bone. Sarah moaned putting her hand on the back of my head and pulling my hair a little.

“Would you like to watch me fuck another man? His big cock fucking me so hard? Could you handle another man pleasing me? Making me cum. Me making him cum.”

She was clearly really getting into this. I had to be honest, I was really turned on too. She was bouncing so hard on my lap. I didn’t know how much longer I would be able to hold my cum. She was covered in sweat from how hard she was working. It was dribbling down her chest and neck. I could taste the salty tang on her skin.

“Baby, tell me you want to watch me fuck a big-cocked hunk. Tell me you want to watch his big cock penetrating your princess. Tell me you want to watch,” she commanded, looking me dead in the eye.

She had stopped fucking me. I was trying to bounce her on my lap but she was holding herself up. So her wet pussy lips were just tickling the tip of my cock. She gave a tug on the back of my head still holding my hair.

“James, I want you to tell me that you want me to fuck another man.” She sounded more serious and even more desperate this time.

I looked up into her beautiful eyes. I was so desperate to cum I would have said anything to get her to keep fucking me. I didn’t really believe she meant it anyway. She was just having fun teasing me. The truth was this new kinky dirty talk was really doing it for me.

“Yea baby, I want to watch you fucking another man,” I said smiling.

Sarah pulled my head towards her face. Our lips met in a deep kiss, but she didn’t start riding me again. She kissed me passionately with tongues for about a minute before breaking apart. I could feel her juices pooled around the base of my cock and she was dripping even more of her nectar onto me.

“Baby, promise me, promise me I can fuck any guy I want. I want you to promise me I can feel another man’s cock in me,” Sarah said teasing the head of my cock with the opening of her pussy.

I paused for a moment. Sarah leaned in and began to plant small kisses all over my neck and chest. I was really desperate to cum and didn’t truly believe she was being serious anyway.

“Ok honey, I promise. You can fuck whoever you want,” I agreed.

Finally, I felt warmth on my cock as she slid onto my stiff prick. I felt the wetness of her pussy running down my cock and over my balls. She started to moan as she bounced on me again. She was bouncing even harder now. Pressing her pussy lips against my pubic bone, then lifting all the way up until my cockhead was just about to pop out before descending again.

The wet squelching noise her pussy was making as she fucked me was so hot. Again I kissed over her shoulders and chest. My face was wet with her sweat. She was really getting a workout in now. Her tight muscles working hard. Her incredible ass slapping against my thighs with a popping noise.

“Thank you, Baby. Thank you for permitting me. I can’t wait to feel another cock in my pussy. Are you going to enjoy watching me? Just imagine me bounding on someone else like this. Their big cock filling my pussy.”

For the briefest of moments that very image burst into my head. I could see in my mind’s eye, the sight of Sarah being impaled on the end of a huge cock. To my great surprise, that image was finally enough to push me over the edge.

I felt my balls tighten, my cock head pulse as I began to spurt into the condom wrapped around my penis. It had been enough to push Sarah over the edge also, as she screamed out in orgasm. She clawed my back, digging her nails into me. She gripped me tightly and I felt her pussy squeezing tight around my cock.

Sarah shook and convulsed on my lap for almost a minute before finally, she rolled off and lay beside me breathing heavy. Lay back on the bed exhausted. That had been one of the hardest fucks we had in a long time. I couldn’t believe how horny she had been.

We were both extremely sweaty, creating a strong musty mix of sweat and sex. Not wanting to go to sleep like this we caught our breath then we got into the shower.

I slipped the condom off my now soft cock. I had to wear condoms because Sarah wasn’t on birth control. She had tried it when she was younger but had discovered that it completely killed her sex drive. When we had first gotten together, we had taken risks going bareback, playing the pullout game. The sex had been incredible and the added risk making it even hotter.

Unfortunately, after a near-miss had to stop with our risky game. Sarah and I had been to a friend’s house for a party. We had had a great time but perhaps had a few too many drinks. We had stumbled home together where we had fallen into each other’s arms.

The sex had been incredible. Sarah had been fucking me, cowgirl. She was bouncing on me so hard, I was squeezing her firm boobs and we were both just about to cum. Sarah had cum first, her orgasmic cries and tensing pussy muscles were enough to finish me off. Drunk, we had not been able to pull ourselves apart. She had fucked me all the way through my orgasm. She had milked every last drop of cum out of my cock.

It was the next morning before the full implications of what we had done hit us. We had waited nervously until Sarah finally got her period. After that, Sarah had forced me to wear condoms. She had not been willing to go back on birth control and I understood. After all, I really didn’t want her to lose her sex drive. She was crazy about sex. We fucked almost every day and the sex was never boring.

As we washed each other’s bodies in the shower, we continued to kiss passionately. Sarah seemed to still be extremely turned on. She was trying to stroke my cock back to hardness. I wanted it to get hard, but I had never been able to get it up so fast after cumming.

Sarah gave up on my stubbornly flaccid cock. We finished in the shower, got out, and dried ourselves. We got back into bed and began to cuddle. We chatted casually for a while before drifting off to sleep.

I awoke the next morning to the smell of delicious food cooking. I got up and pulled on my dressing gown. I walked down the hall and into the kitchen. I found Sarah there in just a thin lacy dressing gown. She looked just as beautiful as the day I met her. She was making some breakfast, French toast my favourite.

She smiled as I walked in. “Good morning, baby. How did you sleep?” she asked in a cheerful voice.

“I slept good, how about you?”

“I slept great, lots of good dreams.”

I noted that she was in an extremely good mood this morning. Which was unusual as she wasn’t usually a morning person. Other than that we had breakfast as normal talking about work and making plans to watch a movie tonight. After breakfast, I went upstairs to shower and get ready for work.

I dressed and headed back down the stairs where I found Sarah standing in the living room, pulling on some leggings to do a workout. The curtains were open and anyone looking in the window at that moment would have got a great view of my girlfriend’s incredible ass.

This wasn’t anything unusual Sarah often got dressed downstairs where anyone walking past would be able to see her. She had admitted to me once it gave her a rush to be an exhibitionist. I don’t know if anyone had actually ever seen her through the window but she still liked the idea it might someday happen.

As she bent over to tie her laces, I took a quick look at her butt. I felt a staring in my groin as I saw the red material become sheer. I could just make out the outline of her white thong buried in the gap of her cheeks.

She stood up and smile at me. “See something you like?”

I nodded, smiling back. I grabbed my coat, kissed Sarah, then said goodbye. During the drive to work, I was thinking about the sex last night. Sarah had been so horny, and the way she had made me tell her I wanted her to fuck another man.

My heart gave a jolt as I remembered what she had made me promise her. I told her that I would let her fuck another man. She was joking, right? Again the image of her bouncing on a bigger cock than mine flashed through my mind. Just then I felt a slight twitch in my cock head.

All the way to work, I couldn’t get that idea out of my mind. I could see as clear as day her fucking a huge cock. She was teasing me asking if I liked watching her fucking a big cock. She was begging to be fucked harder. I could practically hear the sound of skin slapping together.

I was brought back to reality by the sound of a car horn blasting. In my distracted state, my car had drifted across into the wrong lane. I swerved back onto my side of the road. My heart beating very fast. I shook my head trying to clear my mind. I was then suddenly aware of my cock straining hard against my trousers.

Why was I so turned on at the thought of Sarah fucking another man? In truth, this wasn’t the first time I had reacted like this. There had been one occasion before when Sarah and I first met.

We had gotten a little drunk and were playing a truth or dare game on Sarah’s phone. She had selected truth. The question had read, ‘describe your best sexual experience’. Sarah had blushed at first, a cheeky smile on her face. We had not yet had sex with each other and she was still a little shy.

I smiled trying to make her more comfortable. I was hoping this may be the ice breaker that may lead to our first sexual experience. She took a shot of vodka for a bit of dutch courage. The story started with her explaining she and her friends had been on a night out together at a nightclub.

She wasn’t making any eye contact with me. She continued explaining how one thing had lead to another and she had ended up meeting a guy. She had been a little drunk and he came onto her strongly. So strong in fact, she had found herself in a dark area of the club with his fingers inside her panties.

She told me about how she was really horny and wanted to have him there and then. He had taken her out to his car and fucked her right there in the car park. She had reached into his trousers and discovered he had a huge cock. She said she had never been more desperate to have a cock inside her. But she didn’t have a condom so she had just let him fuck her bareback and cum right in her unprotected pussy.

By the time she had finished telling the story, I was rock hard and trying hard to hide the bulge. Sarah had already spotted it and was smiling down at it. She moved closer to me and we began to kiss. We had sex for the first time that night and it was incredible. She was the best lover I had ever had.

Trying to focus my mind again, I began to think about what I needed to do today. I had a busy day ahead at work. The day passed quickly I was just packing up to leave when I got a text message from Sarah.

‘Hey Baby. I hope you are having a good day. I won’t be home when you get there. A few friends and I are going out tonight. I’m going over to Jessica’s to get ready. I’ll text you later. I love you XXX’ I replied right away, ‘OK Baby, have a great night. Talk to you later. Love you too’ I finished packing up and headed for my car. On the way home, I stopped and got myself a pizza. I planned to have a quiet night while Sarah was out. I got home, cracked open a beer, and took a seat on the sofa to eat my pizza. I put on a movie and kicked back.

I was just starting to doze off as I got another text from Sarah. It was a picture of her posing with her friend Jessica. My jaw almost dropped as I saw her. She was dressed in the tightest little white dress that clung to her every curve. She looked incredible. Her boobs bursting out of the top with two hard lumps almost ripping through the material.

It was clear from the photo she wasn’t wearing a bra. Jessica also looked simply stunning. She was dressed in an equally tight red dress, with lacy straps holding her boobs apart, showing the glistening flesh between them.

I felt a slight stirring in my cock as I looked at the photo. They were blowing a kiss down the camera at me.

‘Wow, You two look beautiful, have a great night. Can’t wait to see you when you get home,’ I said in my reply.

A few minutes later, I felt my phone buzzing again. Her message was short ‘don’t worry, I will baby’. There was a winking face with the message.

I didn’t think anything untoward about the message, so I went back to watching TV. It wasn’t long before I dozed off. Hours later I was awakened by another text message. Bleary-eyed I picked up my phone and read the message.

‘Baby, is it ok if I take you up on your offer, tonight?’ I had no idea what she meant. But a moment later a picture message arrived. It was a photo of her and Jessica looking a little drunk. There was a stranger in the photo with them. He was tall, black, and had strong-looking muscles. They both had their arms around his neck giving him kisses on the cheek.

My heart gave a jolt. There was no way she meant what I thought she did, did she? My hands were shaking as I typed a reply. ‘What are you talking about?’ I sat up straight, waiting on her reply, but it didn’t come. I stood up and began pacing the room wondering what could possibly be happening. I would have gone out and got her but I had no idea what club she was in. I picked up my phone and tried calling her, there was no answer.

I was starting to panic. I tried calling again, but again there was no answer. I threw my phone onto the couch and continued pacing about. I couldn’t believe this was happening. Was she just fucking with me? I asked myself. As much as I wanted it to be true, something told me she wasn’t.

Finally, I heard the text tone of my phone. I threw myself onto the couch and lifted my phone. I read the message quickly feeling my heart sinking even further as I did. ‘Baby on my way home now, see you soon.’

“Fuck,” I said out loud. There was no way she was really doing this. My heart was beating very fast as I continued to pace back and forth. For fifteen minutes I walked in circles around the room, hardly able to breathe.

I was starting to sweat. I heard the front door opening. Legs trembling I walked out into the hall. To my horror, two silhouettes were standing in the darkness. Just then the light clicked on. Sarah was standing by the switch smiling at me. Standing beside her was the same tall, strong, black man from the photo.

“James, this is Leon, he’s my personal trainer. You know the one I talk about all the time,” Sarah said not looking at me.

She seemed to be transfixed with the man standing in front of her. He was much taller than me. Six foot four at least, muscular, he looked like he worked out a lot. He was smiling as he put his arm around her.

“Sarah, what are you doing?” I asked with a shudder in my voice.

“I’m taking you up on your offer, Baby,” she replied smiling.

Sarah could clearly tell how nervous I was as she asked Leon if he would go into the kitchen and pour her a drink. She told him where to find our alcohol. He walked past me into the kitchen. Sarah took me by the hand and lead me into our bedroom, closing the door behind her.

I looked at her wanting an explanation. Sarah took a step towards me and kissed me. I resisted at first, but as she pressed her mouth to mine, I felt my lips parting involuntarily. I felt Sarah’s warm wet tongue slide into my mouth. I could smell and taste the alcohol on her breath.

I then felt Sarah reaching for my cock through my trousers. She lightly traced her fingers all over my hardening cock. I could still feel my heart beating very fast. I had to know what was going on. I put my hand on Sarah’s shoulder and pushed her back slightly. We broke our kiss and Sarah looked up at me.

“Sarah, what are you doing?” I asked.

“James, you promised me I could fuck someone else. I thought this was something we both wanted?”

“Honey, I was just joking, I don’t actually want you to fuck someone else,” I said, my voice raised slightly.

Sarah looked suddenly saddened. “But baby, you promised,” she said in a softer voice.

I didn’t know what to say. I couldn’t believe she had really thought I wanted her to fuck someone.

“Baby, why would I want you to fuck someone else?” I asked her.

She looked up at me with big, sad eyes. “But baby, you seemed really into it when we were having sex. I just thought you really wanted it.”

“Baby, that was just in the moment. I didn’t think you were being serious.”

Sarah looked suddenly worried. “Ohh my god, what have I done?” she said sounding terrified. “I just thought you wanted it, and then I saw Leon and well...” she trailed off.

“Well, what?” I asked.

“Baby, I’m so sorry. I thought it would be ok, I thought you wanted me to,” she said in a panicked voice.

“What did you do?” I asked as calmly as I could manage.

Sarah wasn’t making any eye contact with me. I was starting to worry she had done something terrible.

“Baby, I’ve fucked up. I thought you wanted me to be naughty. I let Leon feel my pussy in the club,” Sarah said sounding close to tears.

I didn’t say anything. I took a step back and sat on the bed. I felt as if I was going to be sick.

“Baby, I’m really sorry, I really thought. You told me you wanted me to,” she said pleading.

“Did you do anything else?” I asked trying not to raise my voice. My heart was beating fast.

I was filled with nervous energy, I didn’t quite understand. I watched as Sarah closed her eyes and nod her head.

“Yes baby, I kissed him too. We were dancing and he was pulling me close to him. We were grinding together and he kissed me. Baby, I just got lost in the moment. The next thing I knew, we were alone and his hands were all over me. He was touching my boobs and my upper thigh.” Sarah was breathing heavily as she spoke.

To my surprise, I felt my anger ebbing away. Instead. I was feeling a stirring in my cock. I didn’t say anything and just let her continue.

“He asked me if I wanted him to stop and I said no. So he kissed me, baby, he was such a good kisser. I could feel his finger brushing against my vagina. He was making me so wet baby. My panties are still wet. Then he pulled my panties to the side and began to tease my clit.”

Now I was starting to breathe a little more heavily. I was trying hard to hide my arousal. I didn’t understand why the thought of my girlfriend getting her pussy played with by another man was turning me on so much, but I knew deep down it was. I was meant to be angry with her, but instead, all I wanted to hear was what happened next.

“He was getting me so worked up, I was almost orgasming just from his touch. That’s when I text you. We left the club and Jessica gave us a ride to here,” Sarah said as a tear ran down her face.

She looked over to me and we made eye contact. I knew at that moment that there was a part of me that enjoyed the idea of another man touching my girl. Did I truly want to watch her with another man? Yes, I wanted it more than anything I had ever wanted before. I loved her and I knew this would make her happy.

I leant over and kissed her. This clearly took her by surprise and she flinched away from me. I put my hand on the back of her head and pulled her into my embrace. As we kissed I thought my heart was going to explode. I didn’t understand why I wanted this. All I knew was that I did.

When we broke our kiss. I looked her straight in the eye and said, “Baby, I want you to be happy and if this is what you really want, okay.”

Sarah’s face cracked into a wide smile. “Baby, do you really mean it, but you said...”

“I know what I said but it doesn’t matter. Hearing you talk about what happened in the club and how horny it made you, that made me hotter than I thought possible. I don’t understand these feelings but I know what I want and that’s to see you happy.”

Sarah kissed me again and put her hand on my crotch where she felt my hard cock. She looked into my eyes with the burning desire I loved about her.

“Baby, I love you. Nothing will ever change that. You are everything to me. Thank you for letting me do this. I really believe this is going to be incredible for both of us.”

Sarah stood up and reached for my hand. I took a deep breath and allowed her to pull me to my feet.

“Are you ready?” she asked.

“I don’t know,” I answered honestly.

“Baby, there’s one more thing. Leon doesn’t have any condoms and yours won’t fit him. He says he can pull out before he cums and he’s promised he will.”

“But babe, isn’t there still a risk of you getting pregnant?” I asked. I was starting to wonder if I made the right decision.

“Yes, Baby there is. But if he pulls out before he cums it should be okay. Even if I am ovulating.”

Sarah said the last part with a wicked smile on her face. The naughtiness of the act clearly turning her on. I was even more nervous now but I knew there was no taking it back. As long as he didn’t cum inside her and she washed with spermicide it should be fine ... I hoped.

Sarah smiled and lead me by the hand out of the room. We walked down the hall and into the living room where we found Leon sitting drinking a beer. He smiled at Sarah and completely ignored me.

“Hey gorgeous, I wondered where you got off to,” he said with a shit-eating smile on his face.

Sarah took a seat on the sofa beside him and he put his arm around her shoulder. I couldn’t believe how small she looked beside this man. He was huge, ripped with muscles and even I had to admit he was extremely handsome.

He pulled Sarah close into him and she threw one of her legs over his. For just a moment her legs parted enough for me to get a glimpse of her lacy panties pressed against her pussy. I stood there awkwardly before moving over to the love seat in the corner.
